Claims

[Scope of Claim for Utility Model Registration] (1) Printing is performed by guiding printing paper and ink ribbon to a printing holder, and driving a printing head on this printing holder, and winding the ribbon at a ribbon winding unit. In a printing device that separates the ink ribbon and the print paper by pulling the ink ribbon connected to the printing paper in a direction different from the print paper, the outer surface contacts the ink ribbon between the print holder and the ribbon winding section. death,
and both ends in the longitudinal direction such that when one end in the transverse direction is pulled by the tension of the ink ribbon, the other end presses the printing paper and the ink ribbon against the printing holder. 1. A paper-ribbon separation device for a printing device, characterized in that the paper-ribbon separation device is provided with a separation unit rotatably attached to the printing head. (2) The printing paper and ink ribbon are guided to a printing holder, printing is performed by driving the printing head on this printing holder, and the ink ribbon is combined with printing by winding up the ribbon winding section. In the printing device, the peeling section includes two round bars and a connection that connects the two round bars. and the connecting body is rotatable so that when one of the two round bars is pulled by the tension of the ink ribbon, the other presses the ink ribbon and printing paper against the print holder. 1. A separating device for paper and ribbon for a printing device, comprising: a support supporting the paper and the ribbon. (3) The connecting body of the peeling part consists of two connecting rods that connect both ends of the two round bars, and a connecting plate that connects the middle part of the two round bars, and the support body is a first support that rotatably supports the two connecting rods on the same center line; and a first support that rotatably supports the connecting plate on the same central axis as the rotation center axis of the two connecting rods. 2. A paper and ribbon separating device for a printing device according to claim 2, comprising: a support body;
